3 Claims. (Cl. 20-783) This invention relates to an improved rubber doormat.

An object of this invention is to provide in a door mat an improvedmeans for connecting the rubber mat elements together and securing theconnected mat elements in a rectangular rubber frame.

An object of this invention is to provide improved connecting meanswhereby the mat elements may be firmly secured within the inner marginalportions of a rubber frame without vulcanizing the attaching means tothe frame.

Another object of this invention is to provide in a door matconstruction improved connecting means for connecting the outer portionsof the mat elements to the frame, whereby the mat elements may haverelative movement with respect to the frame.

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention consists of certain novel details ofconstruction and combinations of parts, hereinafter more fully describedand pointed out in the claims, it being understood that changes may bemade in the construction and arrangement of parts without departing fromthe spirit of the invention as claimed.

Referring to the drawing:

Figure 1 is a fragmentary plan view of a rubber door mat constructedaccording to an embodiment of this in vention.

Fig. 2 is a fragmentary sectional view taken on line 22 of Fig. 1.

Fig. 3 is a fragmentary sectional view taken on line 33 of Fig. 1.

Fig. 4 is a perspective view of one of the securing wires for a matelement.

Fig. 5 is a perspective view of the attaching clip for securing theouter portions of the mat structure to the frame.

Fig. 6 is a perspective view of one of the connecting members at thesides of the frame.

Fig. 7 is a sectional view of the frame structure.

Referring to the drawing the numeral 10 designates generally a ribbedmat member which is rectangular in plan. The mat member 10 is providedwith upper and lower ribs 11 and 12 and the mat member at the oppositeends thereof is provided with an enlarged boss 13 through which aconnecting wire 14 engages. The connecting wire 14 secures a series ofoppositely extending mat members 10 together in staggered relation withone mat member extending in one direction and an adjacent mat member 10extending in the opposite direction. The connecting wire 14 is formedinto an elongated rectangular loop having ends 15. A rectangular framegenerally indicated at 16, which is formed of rubber engages about theconnected-together mat elements 10 and the frame 16 is formed of endstrips 17 and side strips 18. The side and end strips 17 and 18 are oflike construction and each is formed of an upwardly and inwardly taperedbody 19 which terminates at its inner end in an inner body C Ra enadflctt,b19571.

2.9; hainmrbndy.zutisr ovided.w th rait qt pa ed longitudinal'slots 21and 22 forming angintermediate longitudinal tongue 23. In order toprovide meanswhereby the ends 15 may be secured in the ends 17 of theframe 16, I have provided U-shaped clips 24 which are adapted to extendover the ends 15 and project into the slots 21 and 22. The clip 24 isprovided with pairs of oppositely extending triangular tangs 25 whichupon inward bending of the clip 24, are adapted to project into thetongue 23. The longitudinal bars 26' of the wire 14 are extended looselythrough the bosses 27 which are formed at the ends of the parallel arms28 of U-shaped members 29. The U-shaped members 29 have a transverselyarcuate bight 30 which as shown in Fig. 2, is adapted to engage on theinside of the bight 31 of clips 24.

In the building up of the mat hereinbefore described the Wire connectingmembers 14 are extended through the mat elements 10 and the length ofthe wire members 14 will determine the length of each side of the mat.The width of each end of the mat is determined by the number of wiremembers 14 which are connected together by alternate mat elements 10, asshown in Fig. 14. The mitered joint between the end and side members 17and 18 of the frame is vulcanized so that the frame will be of solid orintegral frame structure formed of end and side strips. The mat memberswith the wires 10 are then secured within the frame by inserting theclips 24 in the slots 21 and 22 and then compressing the clips 24 sothat the tangs 25 will bite into the tongue 23.

What is claimed is:

1. A door mat comprising a plurality of mat members, each member beingrectangular in plan with transverse ribs on the upper and lower facesthereof, a looped wire extending through the ends of said members, saidwire disposing said members together in staggered relation, arectangular frame about said members, the sides and ends of said framehaving a pair of horizontal slots forming a horizontal tonguetherebetween, a plurality of U-shaped clips extending outwardly of saidwires, said wires extending through said clips on the inner side of thebights thereof, the parallel walls of said clips being disposed in saidslots, and oppositely disposed tangs carried by said walls andprojecting into said tongues.

2. A door mat comprising a plurality of mat members, each member beingrectangular in plan with transverse ribs on the upper and lower facesthereof, a looped wire extending through the ends of said members, saidWire disposing said members in staggered relation, a rectangular frameabout said members, the sides and ends of said frame having a pair ofhorizontal slots forming a horizontal tongue therebetween, each wireforming a rectangular member with the ends thereof confronting the endsof said frame, a plurality of U-shaped clips extending outwardly of theends of said rectangular member, the parallel sides of said cli-psextending into said slots, and tangs carried by said parallel sidesprojecting into said tongues.

3. A door mat comprising a plurality of mat members, each member beingrectangular in plan with transverse ribs on the upper and lower facesthereof, a looped wire extending through the ends of said members, saidwire disposing said members together in staggered relation, arectangular frame about said members, the sides and ends of said framehaving a pair of horizontal slots forming a horizontal tongue, each Wireforming a rectangular member with the ends thereof confronting the endsof said frame, a plurality of U-shaped clips extending outwardly of theends of said rectangular member, the parallel sides of said clipsextending into said slots, tangs carried by said parallel sidesprojecting into said tongues, a plurality of U-shaped members having theparallel 3 arms thereof pivoted to the sides of said rectangular member,the bights of the said U-shaped members being transversely arcuate, andside clips secured to the tongues of the sides of said frame, the bightsof said U-shaped members pivotally engaging the inner sides of thebights of said side clips.
